Race Shop Build: 2020 Pro Circuit Yamaha YZ125

We would submit that the YZ125 is one of the most influential bikes in our sport; so many people have cut their teeth on them and been introduced to the sport through them. The YZ125 is a fast, light, fun, reliable way to enjoy the sport. We wanted to make it faster and even more fun.
Last year, Pro Circuit built Ryan Villopoto a bike for the 125 All-Star races and he did quite well on it. After riding his Straight Rhythm YZ250, and determining it was the fastest 250 weever ridden, we asked Mitch if he would build us a bike like Ryan’s YZ125. “Sure,” he said… “In fact, I think the cylinder and head are back in the race shop. Let’s put it on.”
So, not only did we get the race-spec, we got the exact cylinder and head that Ryan used. That was a hell of a start for this project build.

cant beat the sound of a 125 on the pipe ........

[@markgaudreau8053]

except a 250cc on the pipe

[@straighttimestirrups]

Except a 500 on the pipe!!

[@lewismx8815]

There's something about the alloy frame yz125 that has always been so appealing to me. I've wanted one ever since I started riding.

[@turnerrandolph4256]

Pingree is still an animal on the track! Freaking loved watching that dude ride when I was growing up.

[@chadsugden411]

you always do your best work on a 125 ping. love it

[@LilLefty27]

The yz125 is timeless. Solid bikes

[@RewindThatLive]

just bought a 2020 yz125 and it sounds like the pro circuit exhaust is a must!

[@333studios.]

BRO, I wouldn't go with anything else!!

[@TwistandShout257]

Oh hell yeah! Such a sexy bike! Thank you Yamaha for still making big bike 2 strokes ❤️💨

[@socaloutdoors7355]

After listening to this vid how could anyone ever want or desire an electric motorcycle...?

[@chadrides914]

SoCal Outdoors73 you’ll never have to worry about electric motorcycles. Bombardier killed them all recently. Bought all the patents and buried them.

[@dirtbikeboiz2602]

Haha fuck electric dirt bikes up the 2 stroke

[@yzmoto80]

Double WOW... 1; NICE (REALLY NICE) BIKE !!! 2; DP left RACER-X !? Your still keepin’ it on the pipe Dave ! God Bless !

[@alexzanderarmstrong]

Great video!! Best one yet of this kind! Extra effort on track shots, good editing and good info presentation from ping not just a list of parts 👍😄👍

[@leepercy7339]

Beautiful bike Ping ... nothing sweeter then a 125 two stroke.... Cheers 🇨🇦

[@sethross4954]

Gotta life the sound a a good ol 125

[@Adventure72Awaits]

I have a YZ125. With a Lectron carburetor and reeds this bike is amazing on the trails!

[@yaelpimentel12345]

You use vforce 3 reeds?

[@reelphatties6426]

That is a bad ass 125

[@nickcove7355]

Man that pipe really turned blue.

[@aidenstorovich]

4:27 awesome sound

[@jdm91hatch]

Yes please

[@jamiewilson21]

I didnt get the notification on this banger video

[@ribbledean4111]

I heard the stock reeds were just as good as vforce, I put the FMF set up on my sons an man she barks but nothing like pings 125!! That’s bad ass, pro circuit seems so much more throaty if that makes any sense! Almost sounds like our yz144

[@thelastjapanese2stroker67]

Say...........that's a nice bike!!

[@kjohns236]

Sweet bike! What did you guys do to get the header pipe looking so nice? I want to dress up my PC header too!

[@joenobody2580]

Daaaamn Ping with the fresh Glen Helen track to test on alone 💪 Couple questions : Lectron Carb or no and why ? Has anyone ever not let off going around that famous banked Nascar sweeper ?

[@g.d.4436]

Can't believe no Lectron....they add up everything else, but that's the best carb for no jetting crap.

[@333studios.]

@@g.d.4436 I've also heard and experienced the "pro-circuit jetting" along with the works pipe is just as good as the Lectron. But I've never rode with a Lectron before. Maybe not worth the $450. Same reason to not go with the Vortex ignition. $780 for an increase of 1 HP an 1 Torc. Youll get more out of the bike going into the head ect ect.. idk man.. idk what I'm talking about.

[@HWG-wm8ld]

If I had the money I’d dump a few grand into my yz125, I only have a pc pipe and that’s due to I crushed the stocker. I use my money on fresh tires for every race and fresh oils in the tranny and suspension. I see guys on the line with $1300 4 stroke pipes and all the other bells and whistles, doesn’t do jack when you have worn tires or your suspension is wasted. I’d drop a grand to have glen helen to myself for sure. I’ve had budds creek three times with three buddies and it is heaven.

[@07STINKYBOY]

I would love to see a 2010 yz450f see if the 10 year old 1st year of fuel injection for Yamaha, do a build on it, and see how it keeps up with a 2020 yz450f

[@motokulture4544]

I have an 05 yz125 and I just bought 2016 450 SSS suspension: rear shock with linkage and bolts front shocks with axle bearings and spacers plus from break caliper and the triple tree with clamps bearings and races!!! What do I need to do to make the conversion??? Please and thanks

[@crazypaul3997]

I'm gonna try that tire setup! What PSI you suggest for that tire setup in those conditions?

[@yzmoto80]

Yes please, can I get that delivered with my two day free shipping !?

[@andrewmendoza1578]

Ping working for Vital instead of Racer X now?

[@EverythingisFire]

He moved over two months ago, I believe. Maybe longer.

[@mikebrown41182]

More two stroke! And damn you AMA and FIM and the japanese manufactueres for destroying the sport in 2005. The whole dicplacement was a joke and should have been on a more equal ground! Put a 200 cc two stroke against 250f and 300-325 against the 450 and the sport will become more friendly for the average joe again! And the pro level will be awsome again ! A perfectly tuned two stroke is sexier than any four stroke! More aggressive style and the sound and smell is amazing!

[@ryanrobinson5879]

Ping what's with the extra welds at the fattest part of the exhaust pipe? Did Mitch build a special pipe for that engine package?

[@jamescox6627]

Yes, it's a special pipe.

[@reeveharper8424]

It's a pipe spec that was originally designed for Ryan Villopoto. It has a longer belly. This is because the consumer Pro Circuit pipe for the yz125 is not great and often loses power over stock. I assume this model would be trying to remedy that for their high end racers

[@davidpingree9254]

The modification was done to the mid pipe to make it accelerate quicker, which is what Ryan wanted. The production pipe is better for most because it spreads the power out and pulls a little longer. I haven’t decided which one I like better.... both good, just different.

[@Jas_01101]

Do people paint the Dunlop letters yellow or does the tire come like that?

[@breiland154wilson]

My 2020 yz125 has D.I.D. Rims not Excel and mines all stock ?🤔

[@kieranmacca9370]

Is there anything better than a 125?

[@toddgardner3088]

Is that some kind of "one off" PC pipe?... I just bought one and it doesn't have that double seem mid chamber...

[@kieranmacca9370]

Todd Gardner Villopoto had a custom pipe on his All-Star bike so maybe it’s something that matches the cylinder work Pro Circuit do

[@warclownband]

@@kieranmacca9370 exactly. besides the center section length, looks like the head pipe was lengthened as well. Sure beats the old stacking of exhaust gaskets...lol

[@kieranmacca9370]

Keith Feulner hey man as long as it works lol.

[@EverythingisFire]

What are those clear tube I see under bikes? @5:16

[@davidc606]

EverythingisFire those are from the carb

[@Ron.Bergunnndy]

That's where excess fluid goes out of the bike

[@NathanIsRacin]

Noticed this has VFORCE 4 Reeds. What's the diff between these n the 3's?

[@nickpeccarelli7593]

most likely thickness of petals and shape of them. Depending on the model/year of your bike, they probably don't make the 4's since that's the newest version of them.

[@adone1194]

What helmet is he wearing?

[@nickpeccarelli7593]

I felt/feel more of a difference with the reeds than i did with pipe/silencer. more crisp

[@depweg1092]

I just bought a worn out 2000 yz125 for $750 hopefully I can go through everything and make it new again.

[@chadrides914]

you'll be able to. no worries. Brapppp

[@DJsGarage]

It’s possible. I got a 2002 yz125 for a grand and made it super clean 🧼

[@DJsGarage]

RussGotSauce yes. And you can make a 02+ look like a 2015+ with a steel frame or 2005+ look identical

[@nch-wf3tu]

Tell us about the pipe.... cause it’s not an off the shelf pc pipe!

[@moritzeibl6165]

The yz got DID rims, not excel rims😅. Yz250 has excel rims

Ok so do you have to be a pro to send out your YZ125 to pro circuit

[@jalilpundogar7726]

[@nickpeccarelli7593]

this video was put up yesterday, what the hells with the old TLD SE3 helmet??

[@bsextremesports]

Why can't they ride with an older helmet?

[@nickpeccarelli7593]

@@bsextremesports they can, BUT, the SE4 has been out for over 4 years, not to mention, Ping wears all Troy Lee gear, and has a close relationship with Troy (along with many others in the industry)

Ok you opened a can of worms when you said it's the fastest 125 l ever ridden and if you did that to the other 125s out there the Yamaha would be held back again but l really don't care about those other 125s just the Yamaha and l will be like that tell l die because Yamaha stayed in the game why all the other Japanese companies given up on there two strokes but l know it's all about the money and four strokes sell now days but who wants to spend 10.000 thousand on a dirt bike!!!
